This invention relates to a device especially designed for treatinginsoles of shoes, the primary object of the invention being to formcavities and enlargements on the insole so that the upper surface of theinsole w ll conform to the shape of the bottom of the foot of the wearerto render a new shoe comfortable for immediate wear. This object isachieved by applying pressure-in a single direction substantiallyperpendicular or normal to the plane of the inner bottom of the shoe, sothat in forming depressions therein, no substantial creeping of theinsole nor damage to the fabric and leather of the shoe will take place.In this manner, densification is accomplished without destroying theshape, beauty or wearing qualities of the shoe.

An important object of the invention isto provide a device of thischaracter embodying a support in the form of a last, adjustable membersbeing positioned on the support which members will form the necessarycavities or recesses when pressure is directed to the shoe sole againstthe adjustable members.

Another object of the invention is to provide adjustable members ofvarious sizes, so that cavities or recesses of various sizes may beformed in the surface of the insole.

lVith the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides-in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

Referring to the drawing:

Figure 1 is a side elevational view of a device constructed inaccordance with the invention.

Figure 2 is an enlarged view illustrating the supporting member andcooperating pressing member.

Figure 3 is a bottom view of the pressing member.

Figure 4 is a plan view of the supporting member showing recess formingmembers as adjustably supported thereon.

Figure 5 is a sectional view taken on line 5-5 of Fig. 4.

Figure 6 is a side elevational view of one of the recess formingmembers.

Figure 7 is a partial plan view of a modified form of supporting memberand recess forming member.

Figure 8 is a side elevation view of a recess to receive the threadedshank 10 to which the pressure plate 11 is connected.

A swivel connection is provided between the threaded shank I0 andpressure plate 11, so that the threaded shank 10 may rotate to move thepressure plate vertically, without rotating the pressure plate. A handwheel 12 is secured to the upper end of the threaded shank 10 to rotatethe threaded shank. The base 5 is provided with a socket to receive theshank 13 of the support 14 which is in the form of a shoe last.

Formed in the upper surface of the support 14, are rows of spacedopenings 15 which are arranged adjacent to the edge of the support, asclearly shown by Figure 4 of the drawing. Removable members indicated at16 are positioned on the support 14, it being understood that thesemembers 16 are of various sizes and provided with curved outer surfacesso that the cavities or recesses formed thereby will be curved toconform to the shapes of the toes of the foot positioned in the shoeprovided with aninsole treated by provided =with grooves15 to receivethe in an insole in certain locations to receive the enlargements ofcertain feet.

- Recessessuch as indicated at 18 and 19 respectively, are formed in thesupporting member and provide clearances so that por-- tions of theinsolemaymove into these recesses when pressure is exerted on theenlargements in the formation of recesses in the insole with the resultthat when the insole has been treated by the device, cavities orrecesses will be formed in the surface of the insole while enlargementswill be formed adjacent to certain recesses to the end that the surfaceof the insole will conformto the shape of the bottom of the foot of thewearer.

In the form of the invention as shown by,

Figures 7 and 8, the supporting member is ribs 17 formed on the cavityforming members 16' so that the cavity forming members maybe adjusted tovarious positions on the supporting member.

In the use of the device a pattern is first made of the sole of the footof the person to wear the shoe, the pattern indicating the ex-v actpoints wherecavities should be formed in the insole for the reception ofthe toes or certain enlargements of the foot. Y

' The cavity forming members 16 are now positioned on the supportingmember 14 to conform with the indications presented by the pattern,whereupon the supporting device is positioned in the. base and the shoeplaced over the supporting member in a manner as shown by Figure 1. Thehand wheel 12 is now rotatedmoving the pressure plate 11 into closeengagement with the sole of the shoe, where it may be held" underpressure.

When the threaded shank 10 is moved upwardly releasing the pressure-onthe pressure plate 11 the shoe may be removed from the support 14, andit will be found upon inspection of the insole, that recesses andenlargements are formed therein.

What I claim, is: I

- 1. A device of the class described, including a supporting member,said supporting member having a plurality of parallel and transversecommunicating grooves, and members having ribs adjustablv positioned inthe grooves. said members being adapted to be forced into engagementwith the insole of a shoe to form depressions in the insole.

2. An apparatus for breaking in shoes comprising in combination, asupporting member, an anvil having an area to support the fore part of ashoe, said anvil being mounted on the supporting member and having rowsof openings in the working face about a portion of the margin thereofadapted to receive one or more enlargements to adjustably position thesame, a complemental member cooperating with said anvil, and screwpressure means carried by the support and operable normal to the anvilto press the complemental member in contact with the sole and causelocalized pressure over the elargements.

' 3. An aparatus for breaking in shoes comprising in combination, asupporting member, an anvil having'an area to support the fore part of ashoe, said anvil being mounted on the supporting member and having aseries of'openings in the working'face, said openings being arrangedsubstantially about the outervhalf-sole margin of the anvil adapted toreceive one or more enlargements to adjustably position the same, saidenlargements conforming to and simulating toe and deformed foot shapes,2. complemental member cooperating with said anvil, and screw pressuremeans carried by the support and operable normal to the anvil to pressthe complemental member in contact with the sole and cause localizedpressure over the enlargements. I

4. An apparatus for breaking in shoes comprising in combination, asupp'ortingmember, an anvil having an area to support the fore part, ofa shoe, said anvil being mounted on the supporting member and havingrows of openings in the working face about a por.- tion of the marginthereof adapted to receive one or more enlargements to adjustablyposition the same, a complemental member cooperating with said anvil,and guide means extending above the anvil and normal thereto andpressure means movable in said guide means to press the complementalmember in contact with the sole and cause localized pressure over theenlargements.

In testimony whereof, I hereuntoset my hand.
